Safety Slide Rail Device

This application claims priority to Taiwanese Invention patent application No. 113127575, filed on Jul. 23, 2024, the entire disclosure of which is incorporated by reference herein.

The disclosure relates to a slide rail device, and more particularly to a safety slide rail device.

When an existing slide rail device is to be mounted to a server cabinet, because extension or retraction between slides of the existing slide rail device is unrestricted, a user may be injured by the existing slide rail device. Therefore, there is room for improvement of the existing slide rail assembly.

Therefore, an object of the disclosure is to provide a safety slide rail device that can alleviate at least one of the drawbacks of the prior art.

According to the disclosure, the safety slide rail device includes an outer rail unit and an intermediate rail.

The outer rail unit includes an outer rail that has a sliding surface, and a safety blocking member that is disposed on the sliding surface.

The intermediate rail is slidably disposed on the sliding surface.

The safety blocking member is frictionally engaged with the intermediate rail so as to impede sliding movement of the intermediate rail relative to the outer rail.

Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

It should be noted herein that for clarity of description, spatially relative terms such as “top,” “bottom,” “upper,” “lower,” “on,” “above,” “over,” “downwardly,” “upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

1 2 FIGS.and 1 2 3 illustrate a safety slide rail device according to an embodiment of the disclosure, which is adapted to a server cabinet (not shown). The safety slide rail device includes an outer rail unit, an intermediate rail, and an inner rail.

The outer railhas a sliding surface, and a mounting surfacethat is opposite to the sliding surfaceand that is configured to face the server cabinet (not shown). The safety blocking memberis fixed on the sliding surfaceby two fasteners. In this embodiment, the safety blocking memberhas a main body portion, a resilient arm portion, and a protrusion. The main body portionis formed with an opening. The resilient arm portionextends from the main body portioninto the opening. The protrusionis formed on the resilient arm portion. Specifically, the safety protrusionhas, but not limited to, a dome surface. The safety blocking memberis, but not limited to be, made of one of a metal material and a plastic material.

When the intermediate railcovers the safety blocking member, the safety blocking memberis in frictional contact with the intermediate railso as to impede sliding movement of the intermediate railrelative to the outer rail. In this embodiment, the intermediate railhas a first surfacethat faces the outer rail, a second surfacethat is opposite to the first surface, and an engaging recessthat extends through the first surfaceand the second surface. When the protrusionof the safety blocking memberis substantially aligned with the engaging recessof the intermediate rail, the protrusionof the safety blocking memberis resiliently and removably engaged with the engaging recessof the intermediate rail.

When the protrusionof the safety blocking memberis engaged with the engaging recess, or when the protrusionthe safety blocking memberabuts against the intermediate rail, the safety blocking memberis frictionally engaged with the intermediate railso as to impede sliding movement of the intermediate railrelative to the outer rail. As a result, when the safety slide rail device of the disclosure is mounted to the server cabinet (not shown) by a user, and when the intermediate railcovers the safety blocking member, because the safety blocking memberimpedes the sliding movement of the intermediate railrelative to the outer rail, the user is prevented from being injured.

5 FIG. 2 3 123 23 122 12 2 12 2 3 11 As shown in, as long as a pulling force from the user directly applied to the intermediate railand the inner railis sufficient to disengage the protrusionfrom the engaging recessand is greater than a force deforming the resilient arm portionof the safety blocking membersuch that the intermediate railis moved away from the safety blocking member, the intermediate railand the inner railmay smoothly be pulled to slide relative to the outer rail.

2 12 12 2 2 11 In summary, when the intermediate railcovers the safety blocking member, the safety blocking memberis frictionally engaged with the intermediate railso as to impede sliding movement of the intermediate railrelative to the outer rail. When the safety slide rail device of the disclosure is mounted to the server cabinet by the user, the user may be prevented from being injured, thereby increasing safety for mounting the safety slide rail device of the disclosure.

In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features. In other words, in any described embodiment, when implementation of one or more features or specific details does not affect implementation of another one or more features or specific details, said one or more features may be singled out and practiced alone without said another one or more features or specific details. It should be further noted that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.

While the disclosure has been described in connection with what is(are) considered the exemplary embodiment(s), it is understood that this disclosure is not limited to the disclosed embodiment(s) but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
